  1. 1. FRP shear strengthening of reinforced concrete beams

    Författare :Gabriel Sas; Giorgio Monti; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber reinforced polymers; shear; reinforced concrete; strengthening; model; comparison; literature review; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).

  3. 2. Institutional fragmentation and social service variations : A Scandinavian comparison

    Författare :Dietmar Rauch; Stefan Svallfors; Jonas Edlund; Olli Kangas; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Sociologi;

    Sammanfattning : The Scandinavian welfare states – Denmark, Norway, and Sweden – are usually assumed to constitute a coherent and unique social service model, characterized among other things by a high level of universalism. This thesis questions the existence of such a model. LÄS MER

  4. 3. Covariate Model Building in Nonlinear Mixed Effects Models

    Författare :Jakob Ribbing; E. Niclas Johnsson; Mats O. Karlsson; Janet Wade; Uppsala universitet; []
    Nyckelord :Pharmacokinetics Pharmacotherapy; Pharmacokinetics; Pharmacodynamics; Modeling; Covariate selection; Stepwise selection; Covariate analysis; Methodology; Model validation; Model evaluation; Type-2 diabetes; Beta-cell function; Meta analysis; Cross-validation; Least absolute shrinkage and selection operator; Pharmacometrics; ED optimization; Farmakokinetik Farmakoterapi;

    Sammanfattning : Population pharmacokinetic-pharmacodynamic (PK-PD) models can be fitted using nonlinear mixed effects modelling (NONMEM). This is an efficient way of learning about drugs and diseases from data collected in clinical trials. LÄS MER

  5. 4. Numerical simulation and analysis of multi-scale cavitating flows using a hybrid mixture-bubble model

    Författare :Ebrahim Ghahramani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Homogeneous mixture model; Lagrangian bubble model; CFD; Cavitation; OpenFOAM; Multiphase flow; Hybrid model; Multi-scale;

    Sammanfattning : The aim of this research is to model and analyse multi-scale cavitating flows with a certain emphasis on small sub-grid vapour structures. Cavitating flows include vapour structures with different length scales, from micro-bubbles to large cavities. LÄS MER
